<p>[QUOTE=&quot;desertgem, post: 620397, member: 15199&quot;]Sea water may contain up to about 1 gram gold per 500 tons of sea water. How to separate out was the problem. No real good answer yet. Most promising seem to be to genetically modify some of the microorganisms found near the oceanic vents to take up the gold in giant vats of sea water, and then collect,&nbsp; dry, and burn the microorganisms to leave the gold. Even if they could do it 100% effective, it would not be financially or maybe ecologically sound until all current gold was made radioactive or something. Since gold doesn&#039;t readily corrode or chemically combine with other chemicals at environmental concentrations ( yes can be done in lab), it is easy to reclaim over and over.[/QUOTE]</p><p><br /></p>
